Level AI is a Mountain View-based conversational intelligence company building the AI platform that powers up-to-date contact centers. Our systems analyze millions of customer interactions to surface insights, automate quality assurance, and drive real-time agent guidance. We work at the frontier of applied speech and language AI, and our research directly shapes products used by enterprise customers every day.

We are looking for a Principal AI Research Engineer to set the technical direction for our most ambitious AI initiatives. You will lead research on large language models, speech understanding, and retrieval systems—then translate that research into production capabilities at scale. This is a senior individual-contributor role for someone who thrives at the intersection of cutting-edge research and real-world deployment, and who can raise the technical bar across the entire AI organization.

What You'll Do

-
Define and drive the research roadmap for core AI capabilities spanning LLMs, ASR/speech understanding, retrieval-augmented generation, and agentic systems.

-
Design, train,



fine-tune, and evaluate state-of-the-art models, taking them from prototype to robust, production-grade systems.

-
Lead the architecture of scalable training and inference pipelines that operate reliably on real customer-scale data.

-
Establish rigorous evaluation frameworks, benchmarks, and quality bars for model performance, safety, and reliability.

-
Partner closely with product, platform, and ML engineering teams to ship research into customer-facing features.

-
Mentor senior and mid-level engineers, set technical standards, and act as a force multiplier across the AI org.

-
Stay ahead of the field, evaluate emerging techniques, and represent Level AI's technical work externally where appropriate.

What You'll Bring

-
Degree in Computer Science, Machine Learning, or a related field, or equivalent research experience; typically 6+ years applying ML/AI in production settings.
